To all whom it may concern Be it lknown that I, Piiinir Haas, a citi- .zen of the United States, residing at Dayton,

in the county of Montgomeryand State of Ohio, have invented certain new and useful Improvements in Ventilating Water-Clos! ets; and I do hereby declare the following to 'l y' Abe a full, clear, and exact description'of the f vl1-invention, such as will enable others skilled .1.; 'use the same.

in the nrt to which it appertains to make and My invention consists in the novel fea-- 1 tures hereinafter described, reference being had tothe accompanying drawings which illustrate one embodiment of my invention,

"Qselected by me for the purpose of illustratv ing' the same, and said invention is fully disclosed 4in the following description and My -invention relatesparticularly to. wa-

lten closets in which the bowl is provided witha" discharge passage so constructed as y t0 form aI trap. and normally contain a quantity of water which. seals the trap and prevents e ess of gas from the soil'pipe with which t e trap is directly connected.

Vthe soil pipe,beforetl'ie apparatus is used',v

"The object of my invention is primarily to provide means whereby the liquid seal in the trap canbe broken and a stream of waterdischarged through the empty trap to "so as to act after the ma'nner of an injector andwithdraw volumes of aircontiiiuously 'from and through the bowl and trap and r' 35 discharge the same through the soil ipe to .the sewer for the purpose of ventilating the bowl and preventing any contamination whatever of the atmosphere of 'the room in which the apparatus is located.

In its preferred form,A as for example, in

-the"appaiatus herein shown and described, I

prefer to provide means for moistenin the t'sible that any1' manually operated devices' walls of the 4bowl'above the level o the vwater seal, and which being in contactwith the air, 4become, dry, at the same time that the injector stream is discharged through the trap, for the purpose of breaking the 'water seal and withdrawing the air'in large -uaiitities, through the bowl, and I also preer to provide Imeans for iushing the bowl after it has been used, in the' ordinary man. -Y ner, and for restoring the water seal. In

its preferred form, I provide mechanism for automatically insuring the 'sequence of op? erations above descri ed and as ,it is, os-

the care and personal attention of users of.

the apparatus, I prefer to actuate the apf paratus by the depression of the closet sea". morder that 'the before mentioned automatic and se uential operation of the appatlie necessity for conscious act/or attention on the part of the user. j A It' is to "be noted in connectionwith my improved apparatus that it does not add to or complicate the usual plumbing connections which in most instances would bring about unsanitary conditions and conflict with the severe plumbingregulations controlling the installation of this class of' ap-v paratus. No supplemental or auxiliary ventilating pipe is required, buton-l the contrary air is discharged through thetrap and fsqii pipe to the sewer. It is also to be noted -ratus shall ta e place certainly. and without' I is essential, and continues without interruption until the apparatus is tiushedandthe liquid seal is automatically' restoredj The newl results aocomplishedby'my invention are' very important and '-farreachinn', as they enable an apparatus ofthiskind to Abe installed yin places where they could' fore the normal use of the apparatus, which l V not otherwise be. placed,. as for example, in, A

a sick room, in hospital bedrooms, and the taminating the atmosphere of the room' at any time, and moreover my improved apparatus may be emploved as an active agent for securing the ventilation of the room inl which it is located, for, as will be readily understood, the operation of," the device withdraws 4such large quantities of 'air from and through the-bowl that'by bringin'it into Voperation'lby' hand or otherwise w en :the device is not used inthe normal manner,

the, entire atmospheric 4contents of the r'oom can rbe withdrawn and discharged, thus forcing the room to fill with fresh air vfrom `outside through the doors and windows.

As soon as the valve C- is free from the pas a part flowing downward through the auxiliary outlet cg, pipe b, passage a2 and jet a, and a part flowing into the chamber c and thence downward through the passage e to the main outlet E flushing rirrbjor a preliminary flushing of the bowl. The waterdischarged through the flushing rim will wet the side walls above the water level in the trap and the water flowing through the jet will start the siphonic action of the trap .and empty the trap, the jet nozzlethereafter discharging a strong jet through the empty trap which rge volumes uof air from and through the bowl 'and dis-` air from the room and discharge it through charges the same throu h the soil pipe, thus Lthsoil pipe, necessitating the admission of preventing any contammation of the atmos- Su cient air to the roomthrough the doors ,phere of the room in which the apparatus istwhdajivindows or other o enings therein.

located. The prelimin continues until the ary flushing action iston causes the valve to seat itself against the valve seat c at same and stopping the flow therethrough to ther flushing rim. The flow of water `flough the pipe b however continues and the jet nozzle a? is thus continuously suplied during the entire time that the seat is epressed, thus continuing the Ventilating action. When'the seat is released, the valve f is drawn down upon its seat by the spring ter supply to the chamber c by way of passage L3 isl closed.. The pressure upon the inner face of the valve C will then force the piston P` backward and away fromuthe end of the` passage c2. When thefvalve ci'leaves the seat c at the endl of the passage 02 water from thesupply will flow from D, through el,

s c2 and e, the pipe B to the flushthebowl, cleansing the bowl and ing rim of l V and restablishing the seal thereits outlet,

away from the passage c2 the water in the chamber c is forced outward through passages'ki, F', k to the'valve outlet E,until ts of the valve will resume their normal positions.

It will 'be seen that bythe means herein described, the odor impregnated Aair and gases will pass out through the usual outlet of the closet and 'that these parts of the devic'e will be thoroughly cleansed by the flush- Itwill be further seen that the jet or jets yvater for removing foul air or gases are operation during the entire time that the seat is occupied or; depressed, and thereby ration of m improved closet is made as complete ande ective as possible.

It wiltilmbe seen that instead of a single t and through the pipe B to thef `with the-bowl above' the jet a after Vcontinuously discharging an in jet inthe bottom. of the bowl I lmay use a plurality of the same, an example of such a construction being shown in Fig. 2. ligure twosuch jets a3 and d* areshown. When more than one-is employed, I preferably position Yone or more to direct its current upon the bottom of the outlet to increase the actionlof the outgoing current upon the botteanbf the outlet and assist in carrying rwaly the heavier part-s o f the contents of 'the Jiow .A

It is also appa-rent that my device can be readily applied to clo been set up and used.
